DynamicFluid4 now standard on 2021 NAVIGATORS with Rate Control. The NAVIGATOR’s fluid system (DynamicFluid4) employs advanced fluid dynamics and application rate control to deliver fast response and accurate target rate application. Pressure, flow, pump speed, forward speed, boom sections, and application rate are monitored and processed using advanced computations. The DynamicFluid4 processor analyses the spraying data 20 times a second and provides pre-emptive rate control capability, altering the pump speed with pinpoint precision. The proportional hydraulics used to control the pump speed are highly accurate and smooth but incredibly fast. The liquid system can be operated from the cabin or from the ground.
